'WILLIAM W. BRADLEY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THEKEYSTONE WATCH CASE COMPANY, OF SAME PLACE.

ARTICLE OF JEWELRY OR PLATE.

SPECIFICATION forming part of Letters Patent No. 502,026, dated July 25,1893.

Application filed June 3, 1892; Serial No- 435,340. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM W. BRADLEY, of the city and county ofPhiladelphia and State of Pennsylvania, have invented an Improvement inArticles of Jewelry or Plate, of which the following is a specification.

My invention relates to articles of jewelry or plate, and consists ofcertain improvements which are fully setforth in the followingspecification and are shown in the accompanying metal which thereforecannot be cut into or engraved without danger of cutting into the thincovering and exposing the baseinterior. To ornament such articles Iemploy one or more extremely thin pieces of metal, which may be of adifferent color or shade of color from the surface metal, and pressthese pieces into the surface covering, obtaining thereby highlyornamental effects. These impressed pieces may be properly shaped toproduce any design required. To increase the ornamental effect, theimpressed pieces may have raised, elevated or thickened portions, sothat when the pieces are impressed to bring their edges on a level withthe surface metal the raised or elevated portions extend above thatsurface, and. such raised or elevated portions, because of theirincreased thickness, may be engraved or embossed, so that highlyornamental effects may be obtained. These pieces with raised or elevatedportions may be used as Well with solid as with filled metal articles. Ishall now refer to the drawings for a more detailed explanation of myinvention.

Figure 1 is a plan view of a watch case back or cover embodying myinvention. Fig. 2 is a transverse sectional view of the same manenlarged scale showing the watch case cover 7 formed of filled metal.Fig. 3 is a plan view of a watch case back or cover similar toFig.1illustratingadifferentornamentation. Fig. 4 is a perspective view of awatch case showing an ornamented cover and center. Fig. 5 is a plan viewof the same with a different design upon the cover, and Fig. 6 is-atransverse sectional view of a watch case cover similar to Fig. 2.

A is the part of the watch case which is ornamented, shown in thedrawings as a back or cover.

E, Fig. 4, is a similarly ornamented center.

B, C, D are thin pieces of metal of a color or appearance different fromthat of the surface metal of the part A. One or more of these pieces maybe used according to the variety of colors or effects which it isdesired to obtain. They may be of gold of different colors or tints, ormay be of different metals. These pieces may be cut into appropriateshapes to suit the pattern desired and are soldered to the surface ofthe metal of the part A orE. They are then pressed into the surfacemetal so that their surfaces are on a substantial level with the surfacemetal of the part. These impressed pieces may be subsequently engraved,if desired.

In Figs. 4: and 5 the ornamented surfaces are shown as they appear whensubsequently engraved.

In Fig. 1 I have the figure of a stag at bay. The stag, grass and waterare each composed of a separate piece of different color, and a coloredpicture effect is produced, while the surface of the ornamental piecesis level with the surface metal of the cover.

In Fig. 3 a floral pattern is shown, the pieces B, C, D, being separatedfrom one another over the surface of the cover.

In Fig. 2 the piece B is shown pressed into the surface metal a of thecover, and has a thickness less than that of the thin surface covering.Thus very little metal is required to produce the ornamental effects.

The ornamental effect produced by the inserted pieces of metal may befurther increased by making a portion of the surface of the thininserted pieces raised or elevated as shown at c in Fig. 6 to produceelevated portions of the ornamentation when desired, and

these elevated or ornamented portions may be further engraved orembossed;

Having now described my invention, What I claim as new, and desire tosecure by Letters Patent, is A 1. As an article of manufacture, a pieceof ewelry or plate having an inner filling of base metal and a thinouter covering of precious metal and one or more ornamental pieces ofmetal of difierent character or color from the surface metal, but of athickness less than the thin outer covering of precious metal, pressedinto the surface metal.

2. As an article of manufacture, a piece of jewelry or plate having oneor more pieces of metal of different color having elevated or raisedportions, pressed into the surface metal of the part so that its edgesare on a substantial level with the surface metal of the part to whichit is applied and its raised portions are elevated above said surface.

3. As an article of manufacture a piece of jewelry or plate having aninner fillingof base metal and a thin outer covering of precious metal,and one or more pieces of metal pressed into the surface of preciousmetal and having a thickness at their edges less than the thin outercovering of precious metal but with raised or thickened portions Withinthe edges.

In testimony of which invention I have hereunto set my hand.

WILLIAM W. BRADLEY.
